The command built to generate the list of commits committed but not
authored by a particular individual was incorrect, so some commits
were incorrectly omitted in the table as entries belonging to the
committer.

updated Vagrantfile

Added dbus-x11 requirement (for FF); increased VM memory

Updated ChromeDriver version

The provisioning script used to check for the existence of the
`/opt/edx/node_modules` folder to decide if the installation has already
been completed. However, since additional instructions were executed
by the installer afterwards, any installation error (eg. download
timeouts on low quality connections) happening between the creation of
that folder and the end of the installation wouldn't be recovered from
on the next vagrant instance boot.

Fixed Typo

vagrant:
  - check actual IP;
  - only init machine first time, just as native installations;
  - add .bash_profile to permissions fixup;
  - cleanup excessive newlines in making .bash_profile;

README:
  - include admin & debugging use;
  - info about re-initializing VM & manually running create-dev-env.sh;
  - add django admin & debug_toolbar setting info

Remove the `update_templates command from the installation script, this
command was removed by
https://github.com/edx/edx-platform/commit/3722685e1a185ff4a0a085bb380ed793cf6d1e59

Some parts of the `create-dev-env/sh` script use `$WORKON_HOME` and
others hardcode `$HOME/.virtualenvs` which means if you **don't** put
your virtualenvs under `$HOME/.virtualenvs`, the script doesn't work at
all.

This commit removes the hardcoding of virtualenv location and
consistently uses `$WORKON_HOME` everywhere.

Otherwise, `vagrant ssh` doesn't load the rbenv shims, because that line is in
the .bashrc file.
